Description

Technical Field

[0001] This utility model relates to the field of rapid drainage technology, and in particular to a drainage ditch structure for green belts. Background Technology

[0002] The design and implementation of drainage ditches in green belts aim to effectively guide and drain water accumulated between green belts and roads, thereby increasing drainage efficiency while taking into account the needs of landscape beautification and ecological protection.

[0003] After heavy rainfall during the rainy season, urban flooding occurs. Hard paving materials, such as asphalt and cement roads, which are ubiquitous in cities, have poor permeability, making it difficult for rainwater to penetrate into the ground. This is a major cause of urban flooding. When flooding occurs, the water on the road surface not only greatly hinders traffic flow and causes many inconveniences to citizens' daily travel, but also seriously affects the efficiency of road transportation. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a green belt drainage ditch structure, comprising soil, a placement groove in the middle of the top of the soil, a roadbed on the right side of the top of the soil, the placement groove communicating with the roadbed, a road body on the top of the roadbed, and a green plant layer near the top of the placement groove.

[0005] The placement trough is equipped with a drainage mechanism for quickly draining rainwater from the green belt.

[0006] The top of the main road body is fixedly equipped with a through mechanism for connecting the green vegetation layer;

[0007] The green vegetation layer is equipped with a drainage mechanism to expand the internal rainwater flow range.

[0008] As an improvement to the above technical solution, the drainage mechanism includes a U-shaped drainage ditch, which is detachably installed on the bottom inner wall of the placement trough. A fence-type cover is fixedly installed on the top of the U-shaped drainage ditch. An arc-shaped support frame is fixedly installed in the middle of the inside of the fence-type cover. The bottom end of the arc-shaped support frame is attached to the bottom inner wall of the U-shaped drainage ditch. A filter cotton layer is fixedly installed on the top of the fence-type cover. A layer of expanded clay is provided on top of the filter cotton layer. A green plant layer is provided on top of the expanded clay layer.

[0009] As an improvement to the above technical solution, the through mechanism includes a horizontal slot, which is opened at the top of the road body near the left side. The horizontal slot is movably engaged with a curbstone. The left side of the curbstone is in contact with the ceramsite layer. A drainage hole is opened on the right side of the curbstone at a position flush with the top of the road body. The left end of the drainage hole penetrates the left side of the curbstone.

[0010] As an improvement to the above technical solution, the flow guiding mechanism includes a flow channel, which is opened inside the ceramsite layer. A flow pipe is provided inside the flow channel, and an arc groove is opened on the outer side of the flow pipe near the bottom.

[0011] As an improvement to the above technical solution, a drainage pipe is fixedly installed at the rear end of the U-shaped drainage ditch.

[0012] The beneficial effects of this utility model are as follows: When it rains, the drainage mechanism quickly drains the rainwater from the expanded clay layer. Through the cooperation of the penetrating mechanism and the guiding mechanism, the rainwater on the main road body quickly flows into the expanded clay layer and is evenly discharged. This allows the drainage ditch structure to quickly drain rainwater even in the event of heavy rainfall, effectively preventing water accumulation at the junction of the expanded clay layer and the main road body, thus avoiding the situation where the main road body is flooded. This rapid drainage greatly improves the smoothness of road traffic and enhances the overall operating efficiency of the road. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a green belt drainage ditch structure, including soil 1, a placement groove 2 is opened in the middle of the top of soil 1, a roadbed 3 is opened on the right side of the top of soil 1, the placement groove 2 is connected to the roadbed 3, a road body 31 is set on the top of the roadbed 3, and a green plant layer 45 is set near the top of the placement groove 2.

[0023] The interior of the placement trough 2 is fixedly equipped with a drainage mechanism for quickly draining rainwater from the green belt;

[0024] A through-mechanism for connecting the green vegetation layer 45 is fixedly installed on the top of the main road body 31;

[0025] The green layer 45 is equipped with a drainage mechanism to expand the internal rainwater flow range.

[0026] In this implementation plan, when it rains, the drainage mechanism quickly drains the rainwater on the expanded clay layer 44. Through the cooperation of the penetrating mechanism and the diversion mechanism, the rainwater on the main road body 31 quickly flows into the expanded clay layer 44 and is evenly discharged. This allows the drainage ditch structure to quickly drain rainwater when there is a large amount of rainfall, effectively preventing the formation of water accumulation at the junction of the expanded clay layer 44 and the main road body 31, thereby avoiding the situation where the main road body 31 is flooded.

[0027] Specifically, the drainage mechanism includes a U-shaped drainage ditch 4, which is detachably installed on the bottom inner wall of the placement trough 2. A fence-type cover plate 41 is fixedly installed on the top of the U-shaped drainage ditch 4. An arc-shaped support frame 42 is fixedly installed in the middle of the inside of the fence-type cover plate 41. The bottom end of the arc-shaped support frame 42 is attached to the bottom inner wall of the U-shaped drainage ditch 4. A filter cotton layer 43 is fixedly installed on the top of the fence-type cover plate 41. A ceramsite soil layer 44 is set on top of the filter cotton layer 43. A green plant layer 45 is set on top of the ceramsite soil layer 44.

[0028] In this embodiment, rainwater is quickly discharged from various locations through the coordination of the internal structure of the drainage mechanism.

[0029] Specifically, the through mechanism includes a horizontal slot 46, which is located on the top of the main road body 31 near the left side. The horizontal slot 46 is movably engaged with a curbstone 47. The left side of the curbstone 47 is in contact with the expanded clay layer 44, and a drainage hole 48 is provided on the right side of the curbstone 47 at a position flush with the top of the main road body 31. The left end of the drainage hole 48 penetrates the left side of the curbstone 47.

[0030] In this embodiment, through the cooperation of the internal structure of the penetrating mechanism, rainwater on the main road 31 can quickly flow to the ceramsite soil layer 44 for filtration and discharge.

[0031] Specifically, the flow guiding mechanism includes a flow channel 5, which is located inside the ceramsite layer 44. A flow pipe 51 is installed inside the flow channel 5, and an arc groove is provided on the outer side of the flow pipe 51 near the bottom.

[0032] In this embodiment, through the cooperation of the internal structure of the diversion mechanism, when the rainwater flows into the ceramsite layer 44 through the penetrating mechanism, it can pass through the ceramsite layer 44 evenly, preventing the rainwater from accumulating and falling in one place.

[0033] Specifically, a drain pipe is fixedly installed at the rear end of the U-shaped drainage ditch 4.

[0034] In this embodiment, rainwater in the U-shaped drainage ditch 4 is introduced into the municipal rainwater pipe through a drainage pipe.

[0035] In use, when it rains, rainwater falls onto soil 1, the expanded clay layer 44, and the road body 31. The rainwater on soil 1 and the expanded clay layer 44 passes through the expanded clay layer 44 and the filter cotton layer 43, filtering the rainwater. The water then falls through the fence-type cover 41 into the U-shaped drainage ditch 4. The rainwater in the U-shaped drainage ditch 4 is then introduced into the municipal stormwater pipe through the drainage pipe. When the expanded clay layer 44 encounters rainwater, it becomes heavier. The cooperation between the U-shaped drainage ditch 4 and the arc-shaped support frame 42 increases the supporting force of the fence-type cover 41, thereby preventing the expanded clay layer 44 from collapsing. Rainwater falling onto the main road 31 flows through the drainage holes 48 on the curbstone 47 into the expanded clay layer 44. The rainwater is then guided by the arc groove on the diversion pipe 51 to prevent it from accumulating and falling in one place. The combination of the drainage holes 48 and the diversion pipe 51 accelerates the drainage efficiency of the rainwater, so that the drainage ditch structure can quickly drain rainwater when there is a large amount of rainfall. This effectively prevents the formation of water accumulation at the junction of the expanded clay layer 44 and the main road 31, thus avoiding the situation where the main road 31 is flooded. This water-free state greatly improves the smoothness of road traffic and enhances the overall operating efficiency of the road.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
